I had raised the issue Which Open Source Portal Server to Choose. Jeff replied on his blog in favor of Jetspeed 1. Meanwhile TheServerSide.com also raised the same question referring my blog. So the discussion became interesting. We have seen various responses including responses from nearly all open source portal vendors. As always, it was looking like portal marketplace where everyone trying to promote his portal. So one can ask now, which one you concluded the best? Good question. But if you will see my initial post, you will be able to clarify that I was not trying to find out the best portal server. In fact, it is not possible at all to find the best and come to the consensus. Tell me which is the best Hollywood actress? :-) Anyway, my purpose of that posting was to narrow down the list. For a new person, it is really difficult to choose one portal server out of so many available portal servers. So just to repeat, the objective was to narrow the list not to find the best portal server. Thanks to Dion Almaer and TheServerSide.com for raising the issue on TSS news forum. Without them it would not be easy to get opinion of so many people. Every portal server has it's own pros and cons. Liferay comes with so many ready to use portlets. eXo comes with extendible architecture, and JSR 168 & WSRP support. Jetspeed with Apache's brandname and so on. With the discussion my question has now become a little easy to answer. Now you can decide yourself "which open source portal sever to choose" :-)
